To test whether the predicted epitopes are immunogenic in natural infections, PBMCs were isolated from whole blood samples of 20 HLA-A*02:01-homozygous convalescent patients (labelled A-T) infected with the Wuhan-Hu-1 isolate at the start of 2020 (Supplementary Table S3) and subjected to peptide-stimulated IFN-γ production analysis. The gene discussed is HLA-A; the disease is infection.
